US EPA TechDirect, March 1, 2009
Welcome to TechDirect! March signals the beginning our our 14th   
year delivering TechDirect. We have been very pleased (and   
somewhat surprised) at the continued and steady growth of our   
subscribers over the last 13 years. Since the February 1   
message, TechDirect gained 301 new subscribers for a total of   
32,953. If you feel the service is valuable, please share   
TechDirect with your colleagues. Anyone interested in   
subscribing may do so on CLU-IN at http://clu-in.org . All   
previous issues of TechDirect are archived there. The TechDirect   
messages of the past can be searched by keyword or can be viewed   
as individual issues.  
  
TechDirect's purpose is to identify new technical, policy and   
guidance resources related to the assessment and remediation of   
contaminated soil, sediments and ground water.  
  
Mention of non-EPA documents or presentations does not   
constitute a U.S. EPA endorsement of their contents, only an   
acknowledgment that they exist and may be relevant to the   
TechDirect audience.  
  
CLU-IN Vendor Directory Available for Updates  
  
The CLU-IN Vendor Directory, available online at   
http://www.clu-in.org/vendor/vendorinf ... as part of   
CLU-IN's Vendor and Developer Support area (online at   
http://www.clu-in.org/vendor/). The CLU-IN Vendor Directory is   
now accepting updates and additions from remediation and   
characterization technology vendors. Updates, additions and   
removal requests submitted by March 15, 2009 will be   
incorporated in the next quarterly revision of the directory   
scheduled to be completed by March 31, 2009. Technology Vendors   
are encouraged to use the CLU-IN Vendor and Developer Support   
area as a resource for other methods to promote their tools.   
Site owners, regulators, researchers, and other environmental   
professionals are encouraged to use the CLU-IN Vendor and   
Developer Support area as method to identify vendors and   
services to meet their remediation and characterization needs.  
  
To update existing vendor information to this database. Please

To remove vendor information from the database. Please send an   
email to balent.jean@epa.gov and include a statement in the body   
of the email with your company name and a request to be removed.  
  
The information will be reviewed and included in the next round   
of updates to the vendor directory which typically occurs on a   
quarterly basis. If you have immediate questions, please contact

Upcoming Live Internet Seminars  
  
Tackling the Carbon Footprint at Pump and Treat Projects: A Case   
Study in Energy Efficiency - March 10, 2009, 1:00PM-3:00PM EDT   
(17:00-19:00 GMT). With the goal of advancing knowledge in green   
remediation best practices, over the last year EPA and   
Massachusetts DEP have collaborated to develop an approach to   
reduce the energy usage and carbon footprint at an existing pump   
and treat system. This seminar presents the results of this   
work, including alternatives considered and the final proposal   
of using combined heat and power (CHP) to provide the necessary   
energy to power the system and to increase the efficiency of   
above-ground treatment components. For more information and to   
register, see http://clu-in.org/live .  
  
Frequently Asked Questions Regarding Management of Chlorinated   
Solvents in Soils and Groundwater - March 24, 2009,   
11:00AM-1:00PM EDT (15:00-17:00 GMT). With the goal of advancing   
knowledge in green remediation best practices, over the last   
year EPA and Massachusetts DEP have collaborated to develop an   
approach to reduce the energy usage and carbon footprint at an   
existing pump and treat system. This seminar presents the   
results of this work, including alternatives considered and the   
final proposal of using combined heat and power (CHP) to provide   
the necessary energy to power the system and to increase the   
efficiency of above-ground treatment components. For more

ITRC Performance-based Environmental Management - March 24,   
2009, 2:00PM-4:15PM EDT (18:00-20:15 GMT). Performance-based   
environmental management (PBEM) is a strategic, goal-oriented   
methodology that is implemented through effective planning and   
decision logic to reach a desired end state of site cleanup. The   
goal of PBEM is to be protective of human health and the   
environment while efficiently implementing appropriate   
streamlined cleanup processes. This ITRC training presents an   
overview of what PBEM is, explains how and when to implement it,   
and describes the issues that regulators are concerned about   
throughout PBEM's implementation. Case studies will be presented   
to illustrate successful PBEM projects. The course is valuable   
not only because PBEM is being proposed and implemented at many   
federal and private sites throughout the country, but also   
because PBEM provides an opportunity to enhance all site   
remediation. For more information and to register, see

EPA's Electronic Report on the Environment - Finding,   
Understanding and Using National and Regional Environmental   
Indicators - April 16, 2009, 11:00AM-1:00PM EDT (15:00-17:00   
GMT). This webcast will introduce the audience to EPA's Report   
on the Environment (ROE) project and the Electronic Report on   
the Environment (eROE) web site (www.epa.gov/roe) as a valuable   
resource in understanding what we know - and don't know - about   
trends in air, water, land, human health and ecologic condition   
in the United States. For more information and to register, see

New Documents and Web Resources  
  
Ecological Revitalization: Turning Contaminated Properties Into   
Community Assets (EPA 542-R-08-003). This document provides   
technical information to assist property managers and other   
stakeholders better understand, coordinate, and conduct   
ecological revitalization at contaminated properties during   
cleanup.  Specifically, this document presents general planning   
and process considerations for ecological revitalization and   
provides technical considerations for implementing ecological   
revitalization of wetlands, streams, and terrestrial ecosystems   
during cleanup. This document also highlights EPA's initiatives   
and resources that are available, and presents numerous   
site-specific examples and case studies where ecological   
revitalization has occurred (February 2009, 83 pages). View or   
download at http://clu-in.org/techpubs.htm .  
  
A Guide for Assessing Biodegradation and Source Identification   
of Organic Groundwater Contaminants Using Compound Specific   
Isotope Analysis (CSIA) (EPA 600-R-08-148). When organic   
contaminants are degraded in the environment, the ratio of   
stable isotopes will often change, and the extent of degradation   
can be recognized and predicted from the change in the ratio of   
stable isotopes. Recent advances in analytical chemistry make it   
possible to perform Compound Specific Isotope Analysis (CSIA) on   
dissolved organic contaminants such as chlorinated solvents,   
aromatic petroleum hydrocarbons, and fuel oxygenates, at   
concentrations in water that are near their regulatory   
standards. The traditional approach for monitoring of   
concentrations of contaminants at sites often does not offer   
adequate informatio
